The mechanism of the reaction of HI with methoxymethane involves the following steps:
Step1: Protonation of methoxymethane:


Step2: Nucleophilic attack of I−:


Step3:
When HI is in excess and the reaction is carried out at a high temperature, the methanol
formed in the second step reacts with another HI molecule and gets converted to methyl

Step3:
